Fix hang caused by OUT_ALLOC and remove macro #523

Closed tianjunwork closed 4 years ago

tianjunwork commented 4 years ago
  1. The reason of hang caused by OUT_ALLOC is lack of available output stream buffer. The fix is to seperate the outputBufferFifoInitCount from inputOutputBufferFifoInitCount. And increase its size.
  2. Remove the OUT_ALLOC macro.

looks good! (aside from those test failures which we'll tackle separately)
